Definitions
- Toothbrush having main bristles and having transversely and longitudinally adjustable interdental bristles
- the invention relates to a toothbrush having a grip member and having a cleaning member, which is connected to the grip member and which extends substantially parallel to a cleaning-member longitudinal direction, and having drive means, which are partly accommodated in the grip member and partly in the cleaning member and which include a drivable first drive element and a drivable second drive element in the cleaning member in the area of that end of the cleaning member which is remote from the grip member, and having a drivable bristle holder which holds a plurality of main bristles and which is coupled to the first drive element with the aid of a first coupling element, and having a drivable interdental bristle holder, which holds a plurality of interdental bristles which extend substantially parallel to a longitudinal bristle direction, which is oriented transversely to the cleaning-member longitudinal direction, and which is coupled to the second drive element with the aid of a second coupling element.
- the invention further relates to a cleaning member which extends substantially parallel to a cleaning-member longitudinal direction, and which has drive means, which include a drivable first drive element and a drivable second drive element in the area of one. end of the cleaning member, and which has a drivable bristle holder, which holds a plurality of main bristles and which is coupled to the first drive element with the aid of a first coupling element, and which has a drivable interdental bristle holder, which holds a plurality of interdental bristles which extend substantially parallel to a longitudinal bristle direction, which is oriented transversely to the cleaning-member longitudinal direction, and which is coupled to the second drive element with the aid of a second coupling element.
- drive means which include a drivable first drive element and a drivable second drive element in the area of one. end of the cleaning member, and which has a drivable bristle holder, which holds a plurality of main bristles and which is
- a toothbrush and a cleaning member as defined above are known from the patent document U.S. Pat. No. 5,836,030 A.
- Such a toothbrush has been put on the market by the Applicant and has proved to be comparatively successful.
- it is very important to achieve a good cleaning action in the interdental areas.
- it has proved to be disadvantageous with the known toothbrush and with the known cleaning member that the second coupling element and the second drive element are of a stiff construction and consequently form a more or less rigid unit.
- t a toothbrush of the type defined above in which of the second coupling element and the second drive element, at least the second coupling element is at least partly elastically deformable substantially parallel to the longitudinal bristle direction of the interdental bristles.
- a cleaning member is provided in a toothbrush of the type defined above in which of the second coupling element and the second drive element, at least the second coupling element is at least partly elastically deformable substantially parallel to the longitudinal bristle direction of the interdental bristles.
- an improved cleaning action is achieved at the main tooth areas with a toothbrush in accordance with the invention and with a cleaning member in accordance with the invention, because at these areas the mostly longer interdental bristles recede and, as a result of this, both the interdental bristles and the main bristles, which are disposed directly adjacent the interdental bristles, are capable of providing an intensive cleaning contribution.
- an improved cleaning action in the interdental areas is achieved because the interdental bristles perform not only a movement substantially parallel to the interdental areas but, in addition, can also perform a movement perpendicularly to the interdental areas and perpendicularly to the main tooth areas.
- a toothbrush in which a bristle holder and an interdental bristle holder have been provided but in which neither the bristle holder nor the interdental bristle holder is drivable with the aid of drive elements of drive means and in which the interdental bristle holder is connected directly to the bristle holder.
- the connection between the bristle holder and the interdental bristle holder is elastically deformable, the interdental bristle holder can perform only a pivotal movement defined by the elastically deformable connection between the bristle holder and the interdental bristle holder, i.e.
- a pivotal movement which is dependent on the relative position of the interdental bristle holder with respect to the bristle holder, in other words a pivotal movement having only a comparatively small pivoting radius, i.e. a comparatively short lever arm, which is less favorable for the cleaning of the interdental areas because the interdental bristles perform not only a movement substantially parallel to the longitudinal brush-direction of the interdental bristles but, with their free ends, also a movement oriented transversely to the longitudinal brush-direction of the interdental bristles and transversely to the interdental areas, which is less favorable for a deep cleaning of the interdental areas.
- Both the second coupling element and the second drive element of a toothbrush and a cleaning member in accordance with the invention can be of an elastically deformable construction, which is particularly favorable in order to obtain a lever arm of maximal length.
- a toothbrush and a cleaning member are provided in accordance with the invention wherein the second coupling element is formed by a metal blade spring configuration having a first end portion, an intermediate portion and a second end portion, the interdental bristle holder is connected to the first end portion, and the second drive element is connected to the second end portion.
- the characteristic features are provided in a toothbrush wherein the second drive element consists of a plastic, and the connection between the second end portion and the second drive element is formed by an injection-molded connection and/or wherein the interdental bristle holder consists of a plastic, and the connection between the first end portion and the interdental bristle holder is formed by an injection-molded connection.
- the second drive element consists of a plastic
- the connection between the second end portion and the second drive element is formed by an injection-molded connection
- the interdental bristle holder consists of a plastic
- the connection between the first end portion and the interdental bristle holder is formed by an injection-molded connection.
- the characteristic features are provided in a toothbrush wherein the second drive element and the second coupling element as well as the interdental bristle holder consist of an integral part made of a comparatively hard plastic, and the second coupling element is constructed as a bending element, and at least the second coupling element is embedded in a cover which consists of a comparatively soft plastic.
- the comparatively hard plastic is polyoxymethylene
- the comparatively soft plastic is a thermoplastic elastomer.

- the circumferential pot wall 16 has an aperture 17 , the purpose of which will be described hereinafter.
- a bearing sleeve 18 projects from the pot bottom wall 15 of the head portion 14 and is-integral with the head portion 14 .
- a metal bearing spindle 19 is a press-fit in the bearing sleeve 18 .
- the cleaning member 3 is equipped with a drivable bristle holder 20 , which carries a plurality of main bristles 21 , which for the sake of simplicity are not shown in FIG. 3 .
- the bristle holder 20 consists of a plastic.
- a bearing sleeve 22 is connected to the bristle holder 20 , the connection between the bearing sleeve 22 and the bristle holder 20 being formed by molding around the bearing sleeve 22 .
- the bearing sleeve 22 projects from the bristle holder 20 towards the head portion 14 and is mounted on the bearing spindle 19 , a reciprocating movement in tangential directions being possible between the bearing spindle 19 and the bearing sleeve 22 .
- Locking hooks not shown, project from the bristle holder 20 in radial directions and engage a circumferential groove, not shown either, in the circumferential pot wall 16 , thereby locking the bristle holder 20 in axial directions.
- a coupling pin which extends parallel to the bearing sleeve 22 , projects from the bristle holder 20 towards the head portion 14 and forms a first coupling element 23 of the cleaning member 3 .
- the coupling pin forming the first coupling element 23 projects into the drive socket which forms the first drive element 7 of the cleaning member 3 .
- the bristle holder 20 is coupled to the first drive element 7 and, consequently, to the drive means 5 with the aid of the first coupling element 23 .
- a hold-down ring 24 which extends parallel to the bearing sleeve 22 and to the coupling pin forming the first coupling element 23 , projects from the bristle holder 20 towards the head portion 14 and serves to hold down a second drive element for driving an interdental bristle holder, as will be described in more detail hereinafter.
- a drive pin 25 projects from the bristle holder 20 towards the head portion 14 , which drive pin is connected to the bristle holder 20 by molding and forms part of the drive means 5 , its purpose being described hereinafter.
- the cleaning member 3 is further equipped with a drivable interdental bristle holder 26 , which carries a plurality-of interdental bristles 27 , which extend parallel to a longitudinal bristle-direction 28 , which is oriented transversely to the longitudinal direction 4 of the cleaning member.
- the interdental bristles 27 are merely indicated in FIG. 3 .
- the cleaning member 3 has a second drive element 29 .
- the second drive element 29 has a drive disc 30 having a central slot 31 which is engaged the bearing sleeve 18 , which projects from the head portion 14 , without the actuating movement of the drive disc 30 and, consequently, of the second drive element 29 being impaired.
- a bearing pin 32 projects from the drive disc 30 in a direction towards the pot bottom wall 15 of the head portion 14 in the disc area which faces the tubular portion 8 .
- a first bearing sleeve 33 is a press-fit on the bearing pin 32 .
- the first bearing sleeve 33 cooperates with a stationary second bearing sleeve 34 A, which second bearing sleeve 34 A is locked in rotation to the head portion 14 of the cleaning member 3 by molding.
- a relative movement in tangential directions is possible between the bearing sleeve 33 and the second bearing sleeve 34 A, thus enabling a reciprocatory pivotal movement to be performed by the second drive element 29 .
- the second drive element 29 is axially positioned with the aid of the head portion 14 and with the aid of the hold-down ring 24 .
- a coupling member 34 which is U-shaped in plan view, projects from the drive disc 30 in its area which is remote from the tubular portion 8 , which coupling member is integral with the drive disc 30 and has two limb walls 35 and 36 .
- the drive pin 25 which projects from the bristle holder 20 , engages between the two limb walls 35 and 36 .
- the pivotal movement of the bristle holder 20 causes the drive pin 25 to also perform a corresponding pivotal movement, which the drive pin 25 imparts to the drive disc 30 , and hence to the second drive element 29 , via the coupling member 34 , i.e. via the two limb walls 35 and 36 of the coupling member 34 .
- the second drive element 29 performs a reciprocatory pivotal movement as indicated by the double arrow 38 (see FIG.
- the construction in the area of the bristle holder 20 and in the area of the interdental bristle holder 26 is such that both the second coupling element 39 and the second drive element 29 are partly elastically deformable substantially parallel to the longitudinal bristle direction 28 of the interdental bristles 27 .
- the second coupling element 39 is formed by a metal blade spring configuration.
- the blade spring configuration provided as the second coupling element 39 has a first end portion 40 , an intermediate portion 41 , and a second end portion 42 .
- the interdental bristle holder 26 is fixedly connected to the first end portion 40 .
- the second drive element 29 i.e.
- the drive disc 30 of the second drive element 29 is fixedly connected to the second end portion 42 .
- the connection between the first end portion 40 and the interdental bristle holder 26 which consists of a plastic, is formed by an injection-molded connection.
- the blade spring configuration has a first bent portion 43 in the area of the first end portion 40 .
- the connection between the second end portion 42 of the blade spring configuration forming the second coupling element 39 and the second drive element 29 is likewise formed by an injection-molded connection.
- the blade spring configuration has a second bent portion 44 in the area of the second end portion 42 .
- the second drive element is very stable and rigid in the area of the connection between the bearing pin 32 and the drive disc 30 , and the second drive element 29 is elastically deformable parallel to the longitudinal bristle direction 28 in the area in which the slot 31 is situated, as a result of which the drive disc 30 can deflect in the direction indicated by an arrow 45 in its area where it carries the coupling member 34 , in which case the drive disc 30 is deformed elastically.
- the blade spring configuration forming the second coupling element 39 can readily deform elastically, particularly in its central portion 41 , as a result of which a suitable deflection in the direction indicated by the arrow 45 is achieved in this area. This deflection is limited in that the central portion 41 abuts against the pot bottom wall 15 of the head portion 14 .
- the interdental bristle holder 26 and, consequently, the interdental bristles 27 carried by this holder are movable in the direction indicated by the arrow 45 and the interdental bristles 27 can thus perform movement substantially parallel to its longitudinal bristle direction 28 , which movement is essentially a pivotal movement performed with a comparatively large lever arm.
- Such a pivotal movement capability of the interdental bristles 27 has proved to be very advantageous in view of a proper cleaning action both in the area of the lateral main tooth surfaces and in the area of the interdental spaces between these lateral main tooth surfaces.
- FIG. 4 shows, in the same way as FIG. 1, a part of a toothbrush 1 .
- the toothbrush 1 shown in FIG. 4 is of the same construction as the toothbrush 1 in FIG. 1 as regards the grip member 2 and as regards the tubular portion 8 and the coupling portion 10 of the cleaning member 3 .
- the construction of the mounting arrangement of the bristle holder 20 and the mounting arrangement of the second drive element 29 in the toothbrush 1 as shown in FIG. 4 are different from those in the toothbrush as shown in FIG. 1 .
- the bristle holder 20 has a sleeve-shaped projection 49 and a bore 50 which traverses the bristle holder 20 and the projection 49 and which is stepped in the area of its end which faces the main bristles 21 .
- a bearing sleeve 51 engages in the bore 50 and is curved at its end which faces the head portion 14 .
- a metal bearing pin 52 extends through the bearing sleeve 51 and is secured in the head portion 14 by a press-fit. A tangential reciprocatory movement is possible between the bearing pin 52 and the bearing sleeve 51 .
- the second drive element 29 has a drive disc 30 .
- the drive disc 30 also has a bearing pin 32 which is integral with it.
- the bearing pin 32 is reciprocatingly movable in tangential directions with respect to a bearing sleeve 34 A.
- the bearing sleeve 34 A is immobilized in the head portion 14 by molding.
- the second drive element 29 also has a coupling member 34 , which in the present case is formed by two projections 53 and 54 which extend from the drive disc 30 towards the bristle holder 20 .
- the drive pin 25 engages between the two projections 53 and 54 .
- the second drive element 29 , the second coupling element 39 and the interdental bristle holder 26 form an integral part made of a comparatively hard plastic.
- the second coupling element 39 takes the form of a bending element.
- the bending element forming the second coupling element 39 has a first end 55 and a second end 56 . In the area of the first end 55 the bending element is integral with the interdental bristle holder 26 .
- the bending element In the area of the second end 56 the bending element is fixedly connected to the two projections 53 and 54 of the coupling member 34 , so that in this way the bending element forming the second coupling member 39 is fixedly connected to the drive disc 30 , and consequently to the second drive element 29 , via the projections 53 and 54 .
- the bending element forming the second coupling element 39 is embedded in a cover of a comparatively soft plastic.
- a total of three projections 58 , 59 and 60 project from the second coupling element 39 and are substantially cylindrical.
- an interlocking connection to the cover 57 is realized by means of the three projections 58 , 59 and 60 .
- the third projection 60 at the same time constitutes a limiting stop, which cooperates with a stop surface 61 on the head portion 14 and thus limits a movement of the interdental bristle holder 26 in the direction indicated by the arrow 45 .
- the cover 57 in addition has a cap-shaped extension 62 , which covers a part of the interdental bristle holder 26 and which has a bent portion 64 in the area of its free end 63 .
- the bent portion 64 also forms an interlocking connection, so that altogether the cover 57 is retained properly and reliably.
- the comparatively hard plastic of which the second drive element 29 , the second coupling element 39 and the interdental bristle holder 26 are made is polyoxymethylene.
- the comparatively soft plastic of which the cover 57 is made is a thermoplastic elastomer.
- the movement of the interdental bristle holder 26 in the direction indicated by the arrow 45 is achieved by virtue of the partly elastic deformability of two parts, namely the elastic deformability of the second coupling element 39 formed by the bending element and also the elastic deformability of the drive disc 30 , namely in the area where the two projections 53 and 54 are connected to the drive disc 30 .
- this also results in a comparatively long lever arm for the movement of the interdental bristle holder 26 in the direction indicated by the arrow 45 .
